Billionaire Democratic candidates’ impact on the 2020 presidential race, and the impact of extreme wealth on democracy, are fiercely debated by MSNBC analyst Jonathan Capehart, who has worked on a previous Mike Bloomberg campaign, and whose partner currently works for Bloomberg 2020, and extreme wealth critic Anand Giridharadas, author of ‘Winners Take All.’ Maria Teresa Kumar, president of Voto Latino, also joins Joy Reid to discuss. But first: Bernie Sanders’ win in the Nevada caucus is impacting South Carolina primary predictions, with some questioning whether a Democratic socialist can win this and other key states. Joy Reid and her panel discuss the impact of Sanders’ potential 2020 presidential nomination on the future of the Democratic party. Then: Donald Trump’s impeachment compared and contrasted to the impeachment investigation into Richard Nixon is discussed by former Watergate prosecutor Jill Wine-Banks, who elaborates on this and more in her new book ‘The Watergate Girl.’ Plus: Bernie Sanders winning the Nevada caucus and becoming the 2020 presidential frontrunner is also linked to Bloomberg’s run for president by author and extreme wealth critic Anand Giridharadas, who tells Joy Reid, ‘Something is happening in America right now that actually does not fit our mental models.’ All this and more in this Sunday edition of AM JOY on MSNBC.
